Lab notes (7/26 - 7/30)

Group: Flagella

Incertion of Promoter + RBS in pSB3T5

Done by: Christian and Louise

Parts used: J13002 (promoter+RBS) and pSB3T5

Restriction and Gel extraction

Protocol: [RD1.1]

Notes: We made 2 Restriction mixtures which both were 4 times the mixture in the protocol. We also added 10 ul less water and 10 ul more PCR product than discribed in the protocol

Restriction mixture
- 38 ul Water
- 4 ul EcoRI enzyme
- 4 ul PstI enzyme
- 8 ul Fast Digest green buffer

- 30 ul PCR product (Freeze tube white 25 PROMOTER + RBS)
OR
- 30 ul PCR product (Freeze tube white 29 PLASMID)

Loading:
2 x 21 ul J13002 was loaded on a 2% gel with a 100-1000bp ladder. The Restricted J13002 is 95bp.
2 x 21 ul pSB3T5 was loaded on a 1.5% gel with a 100-10,000 ladder. The restristricted plasmid is 3215bp.

Result:

The picture shows a band around 100bp.


The picture showes two bands, one around 3000bp which is the plasmid and one around 1000bp, which is RFP.

Purification of J13002 and pSB3T5

Protocol:
Notes: four tubes were marked and weighed (all had a mass of 1g). Bands were cut from the restriction gels, added to the tubes and weighed.

Sample capture: 300 ul Capture buffer type 3 was added to the tubes and the tubes were placed at 60 degrees for 20 minutes.
Sample binding:The Capture buffer sample mix were added to MicroSpin Columns, stood for 1 minute and centrifuged for 30 sec. at 16,000g.

The Wash and Dry was carried out according to the protocol.
Elution: 10 ul Elution buffer type 6 was added to the columns, stood for 1 minute and centrifuged for 1 minute at 16,000g. The columns were thrown out and NanoDroped.

NanoDrop:

The Concentrations were quite low, but we pooled them (1P+2P and 3B+4B) and used them for ligation.

Follow-up colony PCR

Date: 26/7
Methods: Colony PCR
Protocol: CP1.3
Experiment done by: Maria, LC

Notes: We made a sample for every plate from the last colony PCR. Out of the 29 samples we could only run 25 at once in the PCR machine. Plate 23 was missing, so there is no sample for it.

Results:
Lengths of PCR products:
1200: 4, 5, 6, 9, 10, 14, 21, 26
1500: 13
1750: 2
1900: 8, 25
2000: 3, 7, 12, 18, 19, 24
2200: 20
2500: 11, 17
Colonies 1, 15, 16 and 22 gave no result.

Analysis: Since we had so many different lengths, we will cut one from each length, specifically colony: 2, 8, 11, 13, 20, 24, 26.
